Nicholas,

The keys are two. First, to use AppleEvent directly instead of  
AppleScript. AS seems to be crippled due to serve user safely. Second,  
prior to quit loginwindow, quit Terminal and Finder. They persist when  
they receive kAEQuitApplication event.

Sending AppleEvent, here's a sample code:

#import	<Carbon/Carbon.h>

- (void)getProcessSerialNumber:(ProcessSerialNumber *)psn  
forApplicationName:(NSString *)name
{
  ProcessInfoRec pir;
  char processName[100];
  const char *cName = [name cString];

  psn->highLongOfPSN = kNoProcess;
  psn->lowLongOfPSN = kNoProcess;
  pir.processInfoLength = sizeof(ProcessInfoRec);
  pir.processName = processName;
  pir.processAppSpec = NULL;
  while ( GetNextProcess( psn ) == noErr ) {
    GetProcessInformation( psn, &pir );
    if ( strncmp( &pir.processName[1], cName, pir.processName[0] ) ==  
0 )
      break;
  }
}

- (void)sendAppleEventClass:(DescType)eventClass  
eventID:(DescType)eventID toApplicationNamed:(NSString *)name
{
  OSErr err;
  ProcessSerialNumber psn;
  AEAddressDesc address;
  AppleEvent ae, reply;

  [self getProcessSerialNumber:&psn forApplicationName:name];
  //NSLog( @"psn:%d %d", psn.highLongOfPSN, psn.lowLongOfPSN );
  err = AECreateDesc( typeProcessSerialNumber, &psn,  
sizeof(ProcessSerialNumber), &address );
  //NSLog( @"AECreateDesc:%d", err );
  err = AECreateAppleEvent( eventClass, eventID, &address,  
kAutoGenerateReturnID, kAnyTransactionID, &ae );
  //NSLog( @"AECreateAppleEvent:%d", err );
  err = AESend( &ae, &reply, kAENoReply, kAENormalPriority, 1000,  
NULL, NULL);
  //NSLog( @"AESend:%d", err );
}

  [self sendAppleEventClass:kCoreEventClass eventID:kAEQuitAll  
toApplicationNamed:@"loginwindow"];
